Matthew Jansen is a 'millennium-child' like you know, he was born in September 2000
The family name 'Jansen' is a german patronym, this is a component of a personal name based on the name of one's father, grandfather or an even earlier male ancestor. 'Jan' is a german male first name, so that means 'Matthew, son of the Jan'. Especially the ending '-sen' is a german one, you can find it mainly in the North German federal states. In each 3 North German federal states live more than 1000 people with the family name Jansen.
Most of our native german boys look like Matthew Jansen

So, you can be sure, Matt Jansen is of German descent.
Trivial, the german version of the name Matthew is Matthäus/Matthaeus & very biblical for us. We don't use it for our children, we take the version Matthias - in german pronounciation this sounds better
